Tissot PRX Carbon 40.5mm
The Tissot PRX Carbon 40.5mm takes the unmistakable design language of the PRX collection and introduces an advanced forged carbon case, creating a lightweight and highly distinctive interpretation of the iconic sports-chic watch.
Reference T137.907.97.201.00 combines a 40.5mm case with a Swiss automatic movement, a black carbon dial, scratch-resistant sapphire crystal and an impressive power reserve of up to 80 hours. The result is a watch that retains the unmistakable PRX character while introducing a much more technical and contemporary personality.
At the heart of the Tissot PRX Carbon 40.5mm is its forged carbon construction. Unlike conventional stainless-steel cases, forged carbon allows the material to display a distinctive pattern, meaning that every case has its own individual visual character. Tissot specifically describes the forged carbon material as lightweight and durable, making it particularly appropriate for a modern performance-oriented interpretation of the PRX.
The black carbon dial continues the technical character of the case, while the transparent caseback provides a view of the automatic movement inside.
The Tissot PRX Carbon 40.5mm is powered by a Swiss automatic movement from the Powermatic 80 family, offering up to 80 hours of power reserve. It also incorporates a patented silicon balance spring, providing an additional technical feature within the movement.

The PRX Design Reimagined in Carbon
The PRX has become one of Tissot’s most recognisable contemporary collections, known for its integrated bracelet aesthetic, angular case architecture and distinctive 1970s-inspired design.
The Tissot PRX Carbon 40.5mm takes that established design and changes one of its most important components: the case material.
Instead of relying exclusively on traditional stainless steel, this model incorporates forged carbon, producing a much more technical appearance.
The material also means that no two cases necessarily display exactly the same pattern. The characteristic forged-carbon texture becomes part of the individual identity of each watch.
This is one of the defining characteristics of the Tissot PRX Carbon 40.5mm.
Rather than simply changing the dial colour or adding a decorative detail, Tissot has used an advanced material to alter the physical character and appearance of the PRX.
The result remains recognisably PRX, but with a more contemporary and performance-inspired personality.
Forged Carbon Case
The forged carbon case is the central feature of the Tissot PRX Carbon 40.5mm.
Tissot uses forged carbon as part of the case construction together with 316L stainless steel. The combination provides the visual character of carbon while retaining the structural qualities of stainless steel in the case architecture.
Forged carbon is particularly interesting because its manufacturing process creates a distinctive marbled pattern.
This means the surface of the Tissot PRX Carbon 40.5mm is not simply a uniform black colour. Instead, subtle variations in the carbon pattern become visible across the case.
Consequently, every individual watch can have its own character.
The material also contributes to the relatively low weight of the watch. Tissot lists the complete watch at approximately 75 grams, which is notably light for a 40.5mm automatic watch.
The lightweight character is one of the reasons the Tissot PRX Carbon 40.5mm feels fundamentally different from a conventional stainless-steel PRX.
40.5mm Case Dimensions
The Tissot PRX Carbon 40.5mm has a case width of 40.5mm, with a length of 40mm and a thickness of approximately 11.23mm.
The proportions preserve the contemporary presence expected from the PRX while keeping the dimensions within a versatile range for everyday wear.
The 40.5mm diameter provides enough wrist presence for the integrated PRX design to remain visually strong, while the carbon construction helps prevent the watch from feeling excessively heavy.
The Tissot PRX Carbon 40.5mm also has a 12mm lug width, contributing to its distinctive integrated case and strap architecture.
The combination of dimensions and lightweight carbon construction creates a particularly interesting balance between presence and comfort.
Black Carbon Dial
The dial of the Tissot PRX Carbon 40.5mm continues the monochromatic technical character of the case.
Tissot specifies the dial colour as black carbon, complementing the forged carbon construction and creating a cohesive dark aesthetic.
The carbon-inspired appearance of the dial works particularly well with the PRX’s geometric design language.
The indexes provide the necessary structure for reading the time, while the hands feature Super-LumiNova® to improve visibility in lower-light conditions.
The result is a dial that remains recognisably PRX while introducing a more technical visual identity.
The black carbon dial also allows the case material to remain the main visual focus.
For someone who prefers contemporary black watches rather than traditional polished steel or brightly coloured dials, the Tissot PRX Carbon 40.5mm offers a particularly cohesive aesthetic.
Swiss Automatic Powermatic 80 Movement
The Tissot PRX Carbon 40.5mm is powered by a Swiss automatic movement from the Powermatic 80 family.
The Powermatic 80 is one of the key technical features of the watch, offering a power reserve of up to 80 hours.
An 80-hour power reserve provides significant practical flexibility. If the watch is removed from the wrist for a weekend, it can potentially continue running through much of the period without requiring manual resetting.
This makes the Tissot PRX Carbon 40.5mm particularly convenient for someone who alternates between several watches.
The movement also features a patented silicon balance spring. Tissot incorporates this technology as part of the movement’s technical specification.
The combination of automatic operation, an 80-hour power reserve and silicon balance-spring technology gives the Tissot PRX Carbon 40.5mm a strong mechanical specification for its category.
80-Hour Power Reserve
One of the most practical characteristics of the Tissot PRX Carbon 40.5mm is its up to 80-hour power reserve.
A long power reserve is especially useful for owners who rotate their watches.
With a traditional shorter-reserve automatic movement, leaving the watch unworn for a couple of days may result in the movement stopping. The Powermatic 80’s extended reserve reduces the likelihood of this happening during shorter periods away from the wrist.
For a watch designed to combine lifestyle, performance and everyday versatility, this is an important advantage.
The Tissot PRX Carbon 40.5mm therefore combines the emotional appeal of a mechanical automatic movement with a level of practical convenience that suits modern watch ownership.
Silicon Balance Spring
The movement inside the Tissot PRX Carbon 40.5mm incorporates a patented silicon balance spring.
Silicon components are increasingly used in modern mechanical watch movements because of their technical properties and resistance to magnetic influences.
Tissot specifically lists the patented silicon balance spring among the movement’s features for this model.
This detail reinforces the technical philosophy behind the watch.
The Tissot PRX Carbon 40.5mm is not simply a PRX with a different case material. The movement specification also reflects the more technically focused character of this particular model.
Sapphire Crystal with Anti-Reflective Coating
Protecting the dial of the Tissot PRX Carbon 40.5mm is a scratch-resistant sapphire crystal with anti-reflective coating.
Sapphire crystal is valued in watchmaking for its high resistance to everyday scratching.
For a watch with such a distinctive carbon dial, protecting the clarity of the display is particularly important.
The anti-reflective coating also helps reduce unwanted reflections from the crystal, improving the readability of the black carbon dial under different lighting conditions.
Tissot specifies the anti-reflective treatment on the bottom side of the sapphire crystal.
The combination of sapphire and anti-reflective treatment contributes to the premium technical specification of the Tissot PRX Carbon 40.5mm.
See-Through Caseback
Unlike some PRX models with a closed caseback, the Tissot PRX Carbon 40.5mm features a see-through caseback.
This allows the wearer to see the automatic movement operating inside the watch.
For a mechanical watch, the transparent caseback adds an additional dimension to the ownership experience. The movement is no longer hidden; it becomes part of the visual identity of the watch.
The see-through caseback is particularly appropriate for the Tissot PRX Carbon 40.5mm, because the automatic Powermatic 80 movement is one of its key technical characteristics.
It also provides a contrast to the front of the watch. From the front, the PRX Carbon presents a dark, highly contemporary aesthetic. From the back, the mechanical movement becomes visible.
10 Bar Water Resistance
The Tissot PRX Carbon 40.5mm has a water-resistance rating of 10 bar, equivalent to 100 metres / 330 feet.
This gives the watch a practical level of water resistance suitable for everyday use.
The 10 bar rating complements the sporty character of the PRX while maintaining the watch’s suitability for a wide variety of daily situations.
The rating should nevertheless be understood as a technical specification rather than a reason to deliberately expose the watch to water unnecessarily.
Regular maintenance and proper care of the seals remain important for preserving water resistance over time.
FKM Rubber Strap
The Tissot PRX Carbon 40.5mm is supplied with a black FKM rubber strap.
Tissot specifies the strap as fluorocarbon rubber, commonly referred to as FKM rubber, with reference T603050081.
The black strap complements the black carbon dial and forged-carbon case, creating a consistent monochromatic appearance.
The rubber construction also reinforces the sporty and technical character of the watch.
A standard buckle provides the closure, while the strap system is designed to be interchangeable.
Tissot specifically notes that the original strap should be used for this model and that other PRX 40mm straps are not suitable for the PRX Carbon.
This is an important detail for owners considering strap changes.
Quick-Release Interchangeable Strap System
The Tissot PRX Carbon 40.5mm has an interchangeable quick-release strap system.
This allows the compatible original strap to be removed more conveniently when changing to another suitable Tissot option.
However, the model has specific strap compatibility requirements because of its carbon case and integrated construction.
Tissot explicitly advises using the original strap designed for this watch and states that other PRX 40 straps are not suitable.
This makes it important to verify compatibility before purchasing an alternative strap.
Lightweight Automatic Performance
At approximately 75 grams, the Tissot PRX Carbon 40.5mm has a particularly light overall weight for an automatic watch of this size.
This is one of the most noticeable differences between the carbon model and conventional metal sports watches.
The combination of forged carbon and rubber means that the watch can provide the wrist presence of a 40.5mm PRX without the weight normally associated with a comparable stainless-steel construction.
The result is a watch that feels contemporary not only visually but also physically.
The Tissot PRX Carbon 40.5mm therefore represents a different interpretation of what a PRX can be: lighter, more technical and more performance-oriented while retaining the unmistakable PRX design.
The PRX Carbon Collection
The Tissot PRX Carbon 40.5mm belongs to the PRX family, one of Tissot’s most recognisable collections.
The PRX design is known for its integrated appearance and its distinctive angular case architecture.
The carbon version pushes that identity in a more technical direction.
Instead of focusing on traditional stainless-steel finishing, the Tissot PRX Carbon 40.5mm uses forged carbon to create a unique surface pattern and reduce weight.
The black carbon dial and black FKM rubber strap reinforce the same philosophy.
The result is a PRX that maintains its original design DNA while presenting a more contemporary and performance-inspired interpretation.
